Be it known that I, FRANK RUDow, afciti'- zen voftlieUnited"States,:residing at Morris,'

inthe county of Grundy and State 'of Illin ois,A have inventedjcerta-in. new and useful Iinpioveinents in "'lanklv Heaters,A of which the following is a sp'eeitioation;

AThis nveiiti'onfielates to appara-tus` for heating water' in s tock-wateringtanks so that itiw'illfbe prevented; from freezing and will always bein 'condition '.or use in cold weather. The invention Yseeks to provide a heater of` sifinpleconstruct-ion whichv inay u sels'olid 'ue'l and will beso Constructed that the: heatingconipartinent thereof may be submerged while access 'inay bereadily had thereto for; th'e'puip'ose of supplying` fuel Y The Y invention lalso;seeks'to provide an effective 'structure which will utilize down ldraft and which will 'provide forr an 'effective .circulationvr to inipartlieat tothe water in the tank and perinit escape ot the products of combustion without' any contamination of the water.' The invention alsov seeks to provide' ineans whereby heated water may :be carried to a supplemental tank 0i' vother more or less re-v niote point of use'. 'These stated ob]ect s,` and other objects which will 'incidentally appear in the course of the `followingl description', are rattainedin such a device as is illustrated in the accompanying clra'iviiig;v and theliiin vention resides in certain ynovel Vrfeatures,

whichwillbe particularly"pointedI out in the appended claims. Inthe drawing: v Eigure l is a' longitudinal vertical` section o'fa tank heater veinbodying niy invention in position fo'r'use,- and n u .Figa 2 is a horizontalA section on the 'line 2'-2of Fig. l.

1I-he tank lv may be ofA any known oi ap'- pioved construction and may be of 'smv pre'- erred dimensions and the heater will be provided in such' sizes as niayv be inost, suitable for tanks of any giveiidiinensions.

The Etwo grate sectionsv are hin gedjly'j con"ne'ctledVV by are Caused' tosnircle theafljaceli CQssbars 8, of Ithe 'twoA grate' fig'aines;V as clearly shown inthe.. drawing When the staten in position, the two grate Sections will project forwardly within the heating chamber or firebex from the rear wall of the upwardly and rearwardly inclined magazine with the base 11 abutting the angle defined by the bottom of theV fire-box or heating chamber and the said rear inclined wall of the magazine, the rear cross bar of the rear grate frame resting against the said rear inclined wall,` as clearly shown in Fig. 1.

The hinged connections between the two sections of the grate permit the grate to be easily placed in position, it being necessary merely to insertthe forward grate through Y the upper end of the magazine and push the same downwardly and forwardly until the forward end of the grate reaches the bottom of the fire-box. Continued pushing upon the rear section of the grate will then cause the two grate sections to turn hingedly relative to each other so that the forward section will slide forwardly over the bottom of the fire-box and eventually assume the position shown in Fig. 1, whereupon the rear grate section will assume Vthe position shown in the same figure and will present a continuous surface to support the fuel. To facilitate the insertion of the grate and t-he withdrawal of the same when necessary, l provide a bar 14 which has a hook 15 at one end and is of such length that it may be pushed downwardly through the magazine so that the hook may be engaged with the grate, whereupon the grate may be pulled from the heater casing.

Hingedly suspended upon the top wall of the magazine 5 above the rear grate section is al door or damper 16 which depends to a point immediately over the grate. An adjusting rod 17 is pivotally attached to this damper near its free lower end and is provided intermediate its ends with a bend l or shoulder 18 which may be easily engaged over the upper edge of the top wall of the magazine, as indicated by dotted lines in Fig. 1, to permit the insertion of fuel or permit the draft to pass over the grate instead of being directed entirely downwardly through the rear end thereof, as is the case when the door is in its pendent position shown in full lines in Fig. 1. The volume of air admitted to the magazine may be controlled by a door or cover 19 which is hinged at one side of the magazine, as shown at 20, and is equipped at its opposite side with a notched latch 21 adapted to engage with a stud or other projection on the side of the magazine whereby to hold the door in any position in which it may be set.

A fire is kindled upon the grate in my improved tank heater in the usual manner and Ythe damper 16 is set, as shown in full lines in Fig. 1, so that` air admitted through the top of the magazine will b e caused to flow downwardly through the rear portion the temperature of the heater casing andthe heat thereby` absorbed by the casing will be radiated therefrom through the body of water in the tank. The magazine may be iilled with fuel to the extent permitted by the doorV or damper 16 and as the fuel upon -the grate is consumed, a fresh supply may be admitted thereto by merely pushing the damper forwardly so that a charge of fuel may pass under its lower edge. After a fire has been kindled and the heater casing has reached the desired state of warmth, the damper may be raised, as indicated in dotted lines, whereupon ther air admitted to the fire-box will mingle with the yfuel in just suflicient quantity to maintain the fire without permitting it to attain such intensity as would be apt to warp lor melt the heater casing. It is to be noted that the bend or shoulder formed in the bar 17 is of such form that it may be engaged upon the upper edge of the top wall of the magazinek Y to support the damper 16 in a raised positionv without requiring the cover 19,Y to be fully opened. My device is exceedingly simple in the construction and arrangement of its parts, may be easily submerged in any tank and will operate efiiciently to maintain the water in condition for use. When ashes are being cleaned from the fire chamber, the door 19 may be swung over and down to rest upon the edge of the tank and bridge the space between the heater and the tank, thereby preventing ashes falling into the water.

Having thus described the invention, I claim:

1. A tank heater comprising a casing including a lire-box and a magazine leading obliquely upward from an end of the firebox, a grate resting on the floor of the iiree',

box with its fuel-supporting surface spaced `above the Hoor and one end extending into the magazine, the fuel-supporting surface being inclined downwardly from the magazine, a damper pivoted at its upper end to the roof of the casing and depending therefrom over the grate, and means for adjusting the damper from the mouth of the magazine.

2. A tank heater comprising a casing including a fire-box and a magazine leading obliquely upward from an end of the firebox, and a grate consisting of sections hinged together at their meeting ends and each having depending supportingmembers of greater vertical dimension at one end of the section than at the opposite end whereby the grate may be caused to slide down the magazine into the fire-box and restupon the floors of the hre-box and the rnagzine at the angie defined by the saine.

3. A tank heater comprising a easing including a fire-hoxmid n.v Casing-leading 0h-v` liquely upward from the viie-iooX, and a grate oonsistimgY of two seetionsnnd a hinge connection between the meeting endsof the sections, both `seetions having depending supporting members each highei` at lone end than it Jlhe opposite endy whereby the fuel- 10 .y
